Transcript of TRANSPORT

AND INFRASTRUCTUREBy: Sabrina, Hayley and JaymeeTRANSPORT Evacuated Tube TransportEvacuated Tube Transport (ETT) could change the way we travel in the future. Using airless and frictionless vacuum tubes, passengers would travel in enclosed pods at speeds of up to 6,500kph, greatly reducing journey times. It would be safer, cheaper and quieter than trains or airplanes.

Negatives- Airline, train and bus companies will lose business - Costs of having it everywhereHypersonic AirlinersHypersonic airliners are already being researched and developed, and could enter commercial service within the next 25 years.This aircraft would have great speed allowing us to fly from Europe to Australia in less than four hours without refueling. They would have excellent subsonic and supersonic fuel efficiency. Hypersonic airliners will be environmentally friendly. Powered by liquid hydrogen, their only waste products will be water vapor and small levels of nitrous oxide.

Another advantage is that, it will be larger than previous jets, they will actually be lighter and could utilize conventional airport runways. They will have moderate take-off noise, too.

The craft will likely be windowless. The heat generated by traveling so fast will make it difficult to install windows that are not too heavy. One solution to this problem might be the installation of flat screen displays projecting images of the scene outside.

Solar Roadways Solar roadways are a relatively new concept. If developed, they would allow highways, roads, parking lots, driveways and pavements to create electricity, using photovoltaic. Traditional asphalt and concrete surfaces could instead be replaced by super-strong, self-healing glass and solar panels capable of being driven and walked upon.Solar Hybrid VesselsIn the near future, the availability of cheap energy is likely to become a major issue as fossil fuels begin to decline. Ship transport will be among the sectors most directly affected. Even if peak oil lies further into the future than currently predicted, another trend coming into play is the need to drastically reduce CO2 emissions.

Both peak oil and global warming have spurred efforts to create new and more efficient ship transport systems. There are many technical and operational means by which this is being achieved. These include new propeller and rudder designs, more flexible use of engines, waste heat recovery, better route planning, improved weather routing systems and autopilots, speed optimization and improved slot time and turn-around systems in ports and canals.

Transatlantic TunnelPositives- Environmentally friendly (clean energy)- In northern climates they could heat themselves with embedded heating elements (similar to the rear window of a car) eliminating ice and snow buildup- No pot holes- A large number of deaths and injuries would be prevented just by keeping the roads safe and dry- LED signage could be built in that responds to traffic, weather, emergencies and other events. For example, if an animal tried to cross, oncoming drivers would be instantly alerted and given plenty of time to slow down.- Electric vehicles could be recharged at any place incorporating solar road panels in their parking lots.Negatives- Costs for maintenance - Damage from the stupidity of hoons - Costs of having cars on the road- All other roads will have to be torn up and replaced with these new 'smart roads'

One hypothetical structure that may become a reality later this century is a transatlantic tunnel. If built, this would allow undersea transit between Europe and North America. At speeds greater than 8,000 kph, passengers could travel from London to New York in less than an hour.

Through the use of nanotechnology, automation and robots, the tunnel could be built surprisingly quickly. It would self-adjust in the event of undersea earthquakes.

The trains would use a magnet system and would operate in a complete vacuum. This would eliminate air friction, enabling them to reach hypersonic speeds.
